Hi,
I am currently adapting the dynamicAlphaContactAngle BC and I want to access transportProperties. I found online (http://albertopassalacqua.com/?p=947) that the following piece of code should take care of that:

// Extract the dictionary from the database
const dictionary& transportProperties = db().lookupObject<IOdictionary>
(
 "transportProperties"
);

// Exctract subdictionary from the main dictionary
dictionary mySubDict
(
 transportProperties.subDict("mySubDict")
);

// Extracting scalar value
dimensionedScalar myScalar(mySubDict.lookup("myScalar"));

However, if I compile the library I get the following error message:

/fhome/OpenFOAM/OpenFOAM-1.7.1/src/OpenFOAM/lnInclude/objectRegistryTemplates.C: In member
function `const Type& Foam::objectRegistry::lookupObject(const Foam::word&) const 
[with Type = Foam::IOdictionary]':newDynAngleFvPatchScalarField.C:153:   instantiated from here
/fhome/OpenFOAM/OpenFOAM-1.7.1/src/OpenFOAM/lnInclude/objectRegistryTemplates.C:130: 
error: cannot dynamic_cast `(const Foam::Time*)((const Foam::objectRegistry*)this)->Foam::objectRegistry::time_' 
(of type `const struct Foam::Time*') to type `const class Foam::objectRegistry*' (source is a pointer to incomplete type) 
make: *** [Make/linux64GccDPOpt/newDynAngleFvPatchScalarField.o] Error 1

I don't really understand the error message. Does anyone know what could be the problem here?
